IMPROVEMENT IN DOUBLE PLOWS.

Specification forming part of Letters Patent N0.3,372, dated December 5, 1843.

To all 'whom it may concern.- f

Be it known that I, PETER RICHAR, of Woosteig in the county of Wayne and State of Ohio, have invented a new and useful Improvement in Plows, which is described as follows, reference being had to the annexed d rawings oi' the same, making part oi' this specification.

Figure l is a perspective View of the combined plows; Fig. 2, an additional cutter 5 Fig. 3, an additional share. Fig. 4 is a View of the under side oi' the mold-board and landside.

This invention and improvement consists in combining with the movable adjustable beam A of .a single plow, B, an oblique adjustable con necting-bar, O, connected by one ofits ends head ofthe standard s oi' the single plow and to the under side of the beam A by the verti cal clevisbolt D, passing through the beam A and the `connectingbar O, being braced by rods or braces E extending from it to the handles K ofthe plow. The additional plow F is secured to the outward extremity oi' the connecting-bar C by a bolt and to the handle K of the plow by an additional handle, G, or curved brace, which extends from the moldboard to the handle K, and which securely i braces it thereto by the connecting-bolt pass` ing through the said curved brace, straight brace E, and handle K.

Between the handles Kof the plow is secured a perforated or notched segment-bar, H, upon which the rear end of the beam moves to the This segment-bar passes through a mortise in the rear end of the beam A, the beam being secured upon it at any angle required by means ofa vertical pin orbolt, I, passed through the beam and segment-bar.

The manner of locking the landside to the mold-board. is peculiar. It is effected by forming a' mortise,N, Fig. 4, in the inside-of the forward part ot the.moldboard, where it is cast thick for the purpose, into which is inserted a corresponding hook, M, formed on the upper and forward part of the landside, and strengthening` the lock by a brace, V,inserted meansof two or more studs, points, or pins, m

w, cast on the mold-board passing through corresponding apertures in the landside, Fig. l.

Another improvement is in making the col- Ler in the manner represented in' Fig. 2, and concave on the back, of' a shape corresponding with the shape ofthe front part of the mold board and landside, where they unite, and in extending said colter up through the head r oi' the standard and through the aperture for the clevis-bolt in the beam A, and fitting the Inoldboard into a cavity, L, in the heel of the colter, being secured by means of a screw-tap, Y, on its upper end turned down upon the top of the beam, and further secured, it' necessary, by means ot' a staple or loop formed on the inside ofthe mold-board, through which thesaid colter is inserted. This colter is made oi' wroughtiron and resembles a common colter from the point to half its length. It then bends bach and forms another curve, which uallows it to pass back of the front edge of the mold-board and by the side thereof, and up through the head or cap r of the sheths and through the beam 'A.

Another improvement is in the manner oi making and fitting the share. This is made as represented in Fig. 3, and is fitted into a corresponding groove made in the outside oi' the lower portion of the mold-board, and is curved over on its upper edge, or made hookshaped, to hook or-lock over the front edge of the mold-board. This share and colter are substituted for the share and colter represented in Fig. 1, and are both made of wrought-iron, and after the share is tted and bolted to the 'mold-board the colter, which is saddle-shaped on its back, is made to straddle the front part of the mold-board and share, and when screwed up firmly by the nut Y binds all the parts firmly and securely together.

The plows thus combined are designed for plowing in grain and stirring loose land of every description, and will perform twice the work of the common single plow.

These plows are easily disengaged and formed into two separate plows, it being only necessary to provide a beam and handles and landside for the additional plow.

The single plow is formed by merely withdrawing the clevis-bolt from the connectingbar and inserting it into lthe head of the standard of the plow B, and adj listing the rear end of the beam-on the segment-bar H, and securing the same at the angle required by the bolt or pin I.

What I claim as my invention, and which I desire to secure by Letters Patent,is-

1. The combination ofthe additional connecting-ball C and plow F and braces E E G with the single plow B,forconverting the latterinto a. combined plow, in the manner and for the purpose set forth.

2. The combination ofthe adjustable beam A with the double plow, in the ina-nner above described.

3. The manner of. looking the landside of the mold-board by ineansvof the hook M, mortise N, pivos m x, and brace V, combined and arrein ged as described.
